Structure Design and Simulation of Full-Rotation Direction Guide Drilling Tool
In order to improve the design efficiency of the full-rotation direction guide drilling tool and shorten the research and development cycle,the author first designed the guidance execution mechanism of the drilling tool,simplified the space mecha-nism model of the guided execution mechanism,and obtained the movement of the mechanism with certainness through the calcu-lation of degrees of freedom.Then the structure composition and guiding principle of the drilling tool are analyzed,and its guid-ance control method is to control the angle displacement relationship between the double eccentric ring and the rotating jacket of the full-rotation direction guide drilling tool,adjust its tool angle and tool surface angle,and realize the guide drilling.Finally.the three-dimensional solid modeling and motion simulation of the virtual prototype of the drilling tool are carried out by Solid-Works and ADAMS software,and the simulation results show that the drilling tool can realize the stepless adjustment of the tool face angle(0~360)°and the tool angle(0~5)°,and verify the feasibility of the designed full rotary direction guide drilling tool structure and guiding principle,and lay the foundation for the processing of the principle prototype.
